MERRITT L. WOOD, OF VALLEY SPRINGS, DAKOTA TERRITORY.

IMPROVEMENTv IN `STOVES.

Specification forming part of Letters Patent No. l 86,286, dated January 16, 1877; application tiled January 6, 1877.

To all whom it may concern:

Be it known that I, MERRITT L. WooD,

erence marked thereon, which form a part of.

this specication.

The object of my invention is to provide an attachment to a stove whereby hay, straw, or shavings can be conveniently burned.

In the accompanying drawings the same letters indicate similar parts.

Figure l shows the side elevation of the stove, the position of receptacle R, magazine M, spring-cap 0head of bolt D, stop-bar'G, ratchet-crank A,ihearth H, forked leg K, the upper part of the stove being the same as any ordinary stove. Fig. 2 shows horizontal section of receptacle, magazine, screw-cap, bolt D, and stop S. Fig. 3 shows front elevation of stove, with the position and opening of receptacle R and stop S.

The fuel is introducedinto the lire-box through the receptacle R. The magazine containing the supply of fuel, consisting of pressed hay or straw, is inserted into the re ceptacle and heldby a pin and right-angled slot, and can be easily detached from the receptacle. The springcap C is likewise attachedor detached from the magazine. When they are both connected, the coiled spring in the springcap C is set at liberty `by turning the bolt D, and the fuel is pressed into the receptacle R, and thence into the lirebox.

. 4The movable stop S, adjusted by the ratchet-crank A and the bar G, is designed to regulate the introduction of the fuel into the lireboxat the mouth of the receptacle, according to the amount of fire desired. The stop is made of perforated conical plates, bars, or

any form adapted to that purpose.

The stop-bar G is held to its place at the side of the receptacle by means of a guide under the ratchet-crank A, and passes through the rear of the fire-box, and'is attached to the stop S, and moves it to or from the mouth of the receptacle.

The hearth H extends under the rear of the stove and back of the receptacle, and is designed to catch any litter caused by replacing the empty magazine with a filled one.

The leg K serves to hold up the rear end of the stove; also, by its forked construction, the magazine.

`The bolt D passes through the center of the spring-cap C, and also through an oblong hole in the plate, to which the front of the spring is attached, and holds the coiled spring within `the spring-cap by means of a cross-pin in the end, when turned at rightangles with the hole in the plate.

The receptacle and spring-cap are preferably constructed of cast-iron, while the magazine may be made of sheet-iron, and should be funnel-shaped, thereby affording less resistance to the passage of the fuel.

Having thus described my invent-ion, what I claim, and desire to secure by Letters Patent, is-

l.v The horizontal magazine M, located beneath the griddle-holes, and connected with the rear of the tire-box, substantially as described, and for the purposes specified.

2. The receptacle R and the spring-cap C, containing spring and bolt D, with magazine M, all arranged and combined substantially as described, and for the purpose set forth.

3. The stop S, having the stop-bar G operated by means of the ratchet-crank A or its equivalent, substantially as described,'and for the purpose specified.

4. The hearth El, located in the rear of the fire-box and underneath the receptacle, substantially as described, and for the purposes set forth.

5. In a stove or furnace, the combination'of the magazine M, receptacle R, stop S, and spring-cap C, arranged and combined substantially as described, and for the purposes set forth.

In testimony that I claim the foregoing as my own I afx my signature in presence of two witnesses.
